test_locale & test_pty fail for 2.4 SVN on Solaris 8/10

[skip]

We are getting a couple test failures at work when building Python 2.4.2 or
the 2.4 Subversion branch on Solaris 8 and Solaris 10 (both on PC hardware).
test_pty fails and test_locale is unexpectedly skipped. The locale
environment is

LC_ALL=C
LC_CTYPE=iso_8859_1

I also tried test_locale with no LC_* environment variables set. Should my
LC_* settings be different? Can anyone else confirm these problems?

Thx,
